Abstract: PURPOSE: A method for regulating the phase of a mobile station in a code division multiple access(CDMA) mobile communication system, is provided to directly input a super-frame phase based on a system time in a synchronization counter, so that time necessary for regulating the phase may be reduced and timing of the mobile station may be promptly secured. CONSTITUTION: A synchronization counter compares a point that a rollover point is generated with a point at which an interrupt signal is generated, by control of a corresponding microprocessor. The microprocessor determines whether or not a phase is regulated. The phase regulation is to check whether or not a PN code index of a mobile station and a super-frame phase are consistent. When the mobile station enters a sleep mode, the check of the phase regulation is performed. If the phase regulation is not necessary, a corresponding operation such as reset of the synchronization counter is performed. If the phase regulation is necessary, the microprocessor resets the synchronization counter. The microprocessor inputs a correct super-frame phase based on a system time in the synchronization counter. The correct super-frame phase is obtained and maintained when the mobile station acquires an initial pilot signal.
